Common failures & inspection points
Visual inspection for corroded areas, dents, distortions, and surface defects on all exposed valve components and connections
Pressure test for tightness with soap/water solution on all joints under pressure; verify blowdown and leakage per ISO 15364:2021 Annex J; document bubble sizes (isolated small bubbles acceptable, numerous larger bubbles indicate exceedance)
Verify valve holds prescribed pressure for minimum 10 minutes; confirm relief pressure setpoint remains within specified range (12 kPa minimum for HS-ISO); inspect internal wear parts without tools per Pres-Vac design
Visual inspection of flame screens (0.65 MESG rating); verify removable elements can be accessed; check for salt deposit, oil accumulation or marine corrosion on flame path; test pressure drop remains within specifications
Verify smooth opening/closing operation without sticking; confirm pressure drop performance matches baseline; inspect sealed internal components for water ingress or debris; test responsiveness to pressure changes
